Abstract

Ein Drucksteuerventil (1) weist einen ersten Steuerkolben (1) auf, der zwischen einem an den ersten Steuerkolben (1) angrenzenden, mit zumindest einer Arbeitsleitung verbundenen (A, B), ersten Druckraum (6) und einem an den ersten Steuerkolben (1) angrenzenden zweiten Druckraum (7) angeordnet ist und der von einer ersten Vorspannungsfeder gegen (4) gegen einen Anschlag (3) gedrückt wird. Eine Drossel (8) verbindet den ersten Druckraum (6) und den zweiten Druckraum (7) miteinander. Der zweite Druckraum (7) ist mit einem zweiten Steuerkolben (11) verbunden, der von einer zweiten Vorspannungsfeder (17) vorgespannt wird, und der bei Überschreiten eines vorbestimmten Drucks in dem zweiten Druckraum (7) soweit verschoben wird, daß eine Steuerkante (12) des zweiten Steuerkolbens (11) eine Verbindung des zweiten Druckraums (7) zu einem Hydraulikfluidabfluß (23) freigibt. Der erste Steuerkolben weist (1) eine Steuerkante (2) auf, die bei Verschiebung des ersten Steuerkolbens (1) gegen die erste Vorspannungsfeder (4) eine Stelldruckleitung (5) mit einen Hydraulikfluidabfluß (23) verbindet. Auf den zweiten Steuerkolben (11) drückt ein mit einem Steuersignal geregeltes Stellglied (15) gegen die zweite Vorspannungsfeder (17).
